TriCal | Measuring position repeatability of an industrial robot

Repeatability is one of the most important characteristics of industrial robots, it determines the ability of the robot to achieve the same targets over and over. According to the ISO 9283, repeatability of the industrial robot must be measured at five specific points in the largest cube inscribed in the robot’s workspace. In practice, however, performing an ISO test is not always easy and fast as it requires non-restricted access to the workspace, as well as advanced measuring equipment, such as a laser tracker. As an alternative, we have developed the TriCal - affordable and precise 3D measuring instrument that makes it easy to evaluate position repeatability of the robot in the target workspace. In this video, we demonstrate the repeatability performance evaluation of the KUKA KR6 R700 sixx industrial robot arm.

The TriCal has been developed and manufactured at École de technologie supérieure under the supervision of Professor Ilian Bonev.
